Here's a screen shot of mine, just in a ways from Cache Bay on the east end of the Q. The base map generally shows portages at least in the BWCA and the Q. It doesn't have Canadian locations, but you can upload gpx files so I saved a gpx file of my route that included campsites, and uploaded that. On the trip, I could follow my uploaded route and see uploaded campsites, and use the map's portage markings.
